Heavy rainfall is one of the most damaging natural hazards. It can overwhelm drainage systems and cause severe flooding, damaging homes, businesses, transport networks and other critical infrastructure. Effective risk management can help reduce these impacts and strengthen resilience.
Effective preparedness begins with the early involvement of all relevant stakeholders. In addition to drainage and public works departments, urban planning, transport planning, parks and green space management, fire services, civil protection authorities and higher-level water authorities should all be engaged. A designated point of contact can help coordinate activities and ensure transparency throughout the entire process.
Early engagement with residents helps build acceptance of planned measures and creates an open dialogue about opportunities, limitations and priorities related to heavy rainfall preparedness.
A thorough assessment of the municipality's catchment area forms the foundation of any heavy rainfall strategy. Existing drainage plans can be enhanced through analyses that specifically consider heavy rainfall scenarios.
The results help municipalities to:
Heavy rainfall preparedness is not a one-off exercise. Municipalities should regularly review and update their strategies to reflect new insights, changing conditions and lessons learned from extreme weather events.
Only through continuous review and improvement can communities strengthen their resilience to future heavy rainfall events.
